Ensure tire is totally deflated before removingwheel locknuts. Never use tubes in wheel assemblies. Rim surfaces must be kept clean and free of rustand dirt. Never use wheel assemblies with damagedstuds. Never inflate a wheel assembly with the wheellocknuts removed. Never inflate a wheel assembly without firstchecking wheel locknut torques. Do not exceed recommended tire inflationpressure. Always use a tire inflation cage and a clip-on airchuck for tire inflation. Ensure runflat compressor strap is centeredaround runflat. Never install radial tire on eight bolt wheel. Do not mix radial and bias tires.This task covers:a. Disassemblyc. Repairb. Inspection and Cleaningd. Assemblya. DisassemblyWARNINGDo not use tire machine. Injury to personnel or damage to equipmentmay result.NOTEThe following maintenance procedure applies to vehicles using load range"D" tires and one-piece rubber runflats. Refer to paras. 8-4 and 8-4.1 formaintenance instructions on bias tires and magnesium runflats.1.Place wheel assembly in a tire inflation cage.WARNINGIn all disassembly operations, ensure the tire is totally deflated beforeremoving wheel locknuts. Failure to follow proper safety precautionscould cause serious injury or death.2.Remove valve core (8) from valve bore (9) and deflate tire (6). Run a piece of wire through valvebore (9) to make sure it is not plugged.3.When tire (6) is fully deflated, use a circular pattern and loosen twelve wheel locknuts (2) securingrim halves (1) and (4) together. If you hear escaping air, do not proceed. Wait until the sound stopsand recheck valve bore (9). When you are certain the tire (6) is fully deflated, proceed to removewheel locknuts (2). Discard locknuts (2).TM 9-2320-280-20-28-16Change 2
